Sinkhole session (NH 8.6) at EGU 2012
we would like to draw your attention on the following forthcoming
Scientific Session on Sinkholes at the General Assembly of EGU in
Vienna, next April:
Session NH8.6 "Sinkholes: from susceptibility to risk evaluation and
mapping" at EGU General Assembly (Vienna, 22-27 April 2012)
Convened by: Mario Parise, Giulio Iovine, Stefania Nisio
Sinkholes are widespread in many countries of the world, in several geological and morphological settings, affecting distinct lithotypes either in the detrital cover sequences or in bedrock outcrops. In particular, some phenomena develop in geomorphological context characterized by plain areas and notable detrital coverages, either made of sediments or colluvial or residual terrains, thick even tens to hundreds of meters. In some cases, the genetic mechanisms are poorly understood; they can be quite complex and appear not directly connected with classical karstic processes. The recent urban development and the increasing need of spaces for infrastructures in areas potentially affected by sinkholes require a better comprehension in terms of related susceptibility, hazard and risk. The session aims to stimulate the discussion on the state-of-the-art of the studies on the mentioned topic, with special regard to sinkholes in plain not-karstic areas. Analyses of genetic mechanisms, methodological examples of investigation, and case studies are welcome, as well as description of techniques for evaluating susceptibility, hazard and risk.
Note: A selection of studies presented at this session will be considered for publication in a special issue of a relevant international journal.

3D Modelling (geometry and connections) of carbonate massifs in structurally complex areas : An application to buried karst reservoirs of Languedoc (South France) More details here Karstic reservoirs offer new opportunities to secure water resources in the populated and arid regions, such as the Mediterranean Karstified Jurassic carbonate massifs presently buried beneath Cenozoic cover have been studied in the south of France by BRGM, and more recently by Husson (2013) Objective The objective is to develop a method to determine the 1) distribution, 2) connectivity and 3) intensity of karstification of the carbonate massifs, including buried karsts The study area (Languedoc) incorporates the previous (Husson, 2013) study and extends south-westward, ie downstream of the watershed This study area is well suited for developing and validating the method (good data coverage & known geodynamic evolution), which can then be exported, especially in Mediterranean region Operations 1- Construction of a 3D geological model of this poly-deformed area; the model will include all geological information concerned with the (paleo)karsts and (paleo) base-level indicators Surface geology, 2D seismic reflexion, exploration borehole data, gravimetry will be compiled and integrated, within the BRGM-Intrepid “Geomodeller” While building the geomodel, tests of consistency of 2D restoration of random lines (using Schlumberger-Igeoss “Dynel2D”) will provide a validation of the geomodel Additionnal validation will be secured by gravity inversion of the geomodel and comparison with available measured gravity data 2- Sequential 3D restoration of the geomodel, at successive times of documented karstification (Messinian, Late Miocene, Early Paleocene, Mid-Cretaceous), using Schlumberger-Igeoss “Dynel3D” Restoration will provide for each period : the flow-lines within the massifs from upstream topography towards the outlet, whether it is surficial (over impervious formations) or karstic (through carbonate massif) drainage Karstified and non-karstified (above and below base-level, respectively) carbonate massifs will be delineated within the restored geomodels, for each karstification periods 3- These paleo-base levels, obtained at the different stages of karstification will be input in the present day geomodel, in order to determine the distribution of karstified portions of the carbonate massifs (located above paleo base-level) The output will be the volume of potentially karstified massifs and the distribution of superimposed karsts, the later being an indication of increased karstification 4- Gravity inversion of the 3D geomodel (with BRGM-Intrepid “Geomodeller”) provides density distribution We suggests that lower density values within the carbonate formations, correlate with karstified areas The gravity inversion results will be analysed (qualitatively & quantitatively) and correlated with the distribution of karstified massifs derived from the previous stage 5- The findings will be analysed and tested in the light of regional hydrogeological data Applications: - Exploration of karst reservoirs (water, oil & gas, mining industry) - Management of karst reservoirs (water supply, hydrothermal resorts, gas storage, geothermy). ...
